When I run $ npm run watc

Answer 1

instead of using this

Vue.component('tabs', {
    template: `
        

          

            
Pictures
            
Music
            
Videos
            
Documents
          
        

        

          
        
    `,
});

you should use

Vue.component('tabs', {
    template: `
      

        

          

            
Pictures
            
Music
            
Videos
            
Documents
          
        

        

          
        
      
    `,
});
